Introduction of Mitsubishi PLC series

Comfortable operating environment for Mitsubishi inverter FR-A800

1. For the switching input and output circuits, pay attention to the consistency criterion of maintaining the state; The positive logic criterion is usually used, that is, when the input and output are live, it is in the "ON" state and the data value is "1"; Conversely, when the input and output are powered off, it is in the "OFF" state and the data value is "0". Such...

1. Enter the wiring (1) The input wiring should generally not exceed 30 meters. However, if the environmental disturbance is small and the voltage drop is not large, the input wiring can be appropriately longer. (2) The input/output lines cannot be separated by the same cable, and the input/output lines should be separated. (3) As far as possible, choose normally open ...

1. If the PLC stops in the middle of some outputs where the output is excited, then look for the signal that caused the next operation (input, timer, line, drum manipulator, etc.). The programmer will show the ON/OFF status of that signal. ...

The three output types of PLC are: transistor output, thyristor output and relay output, what is the difference between these three different output types? (1) Transistor output: The big advantage is that it is accustomed to high-frequency action, and the echo time is short, generally about 0.2ms, but ...

There are several ways to classify frequency converters: According to the classification of the main circuit operation method, it can be divided into voltage-type inverter and current-type inverter; According to the classification of switching methods, it can be divided into PAM control inverter, PWM control inverter and high carrier frequency PWM control inverter; In accordance with the ...

The servo system is an automatic control system that enables the output of the object's orientation, direction, and state to change with the arbitrary change of the input quantity (or given value). In the automatic control system, the system that can echo the control signal with a certain degree of accuracy is called the follow-up system, also known as the servo system.

Generally, there are three types of Mitsubishi PLC output circuit methods, namely: relay output type, transistor output type and thyristor output type. So what are the characteristics of each of them? First, the relay output circuit Use of relays ...

1. The digital-to-analog converter is a system that converts digital signals into imitation signals, which can generally be completed by low-pass filtering. The digital signal is decoded in the first line, that is, the digital code is converted into the corresponding level to form a stepped signal, and then the low-pass filter is carried out. According to the signal and system ...

1. Occasions with brake servo motors: The servo motor is mainly loaded by the motor shaft, assuming that the load driven by the motor shaft is vertical, after the whole control system is powered off, the load on the servo motor shaft will be driven to run down under the action of gravity, so that ...

Many novices in the electrical industry are not sure how to start debugging after completing the planning links such as electrical control cabinets and PLC programs. Perhaps some people due to inappropriate debugging methods have led to PLC burning and other problems, so how should the planned electrical system be debugged? Follow these seven steps. ...

1. Question: What is the type of RS485 to RS232C converter used by Mitsubishi inverter for communication? Solution: FA-T-RS40* Mitsubishi inverter is available. 2. Question: Mitsubishi inverter frequency external potentiometer is given, and the external potential recommended to be used ...

Mitsubishi inverter has many setting parameters, each parameter has a certain selection scale, and the inverter can not work normally due to improper setting of a single parameter in the application. Let's take a look at the Mitsubishi inverter parameter setting operation. ...

The encryption process is as follows: ** Open the serial port for the first time [00000000] IOCTL_SERIAL_SET_BAUD_RATE Baud Rate: 9600 (Set baud rate here) [00000000] IOCTL_SERIAL_SET_LINE_CONTROL StopBits: 1, Parity: Ev ...

Component conversion is a process in which an analog signal (load converter output voltage) input from outside the programmable controller is converted into a digital output value and a total component output value, and then stored in buffer memory. After the conversion process, the conversion completion (XE) will change to ON, and the transformation completion mark (Un\G1 ...

1. When the PLC and the host computer (or touch screen) form a monitoring system, there are many hours on the screen that require "manual", "active" and other control forms (generally more than one). In the program, you can use the "MOV" command. For example, when selecting "manual", the constant 1 MOV will be changed to a ...

MELIPC's intelligent industrial control product system includes MI50000 analysis categories, MI2000 monitoring strain, and MI1000 gateway category, forming a full range of data collection, processing, and transmission solutions between the FA production site and the IT system, and using edge accounting to complete the self-discipline and sloppy IoT layout.

It has become an irreversible trend to drive the motor through the inverter, and in the actual application process, because the matching relationship between the inverter and the motor is not very reasonable, it often leads to some problems. When selecting an inverter, you should fully understand the load characteristics of the equipment driven by the inverter. Ms. Ginseng ...

First, the control accuracy is different The step angle of the two-phase hybrid Mitsubishi servo motor is generally 1.8 ° and 0.9 °, and the step angle of the five-phase hybrid Mitsubishi servo motor is generally 0.72 ° and 0.36 °. Mitsubishi servo motors are also smaller in some functions according to the segmentation. Such as Sanyo ...

1. Tension Manipulator Principle - Introduction The tension manipulator can be called the tension manipulator, which is usually used with magnetic particle brake, magnetic particle clutch and tension detector, and is suitable for winding, unwinding, tension control, etc. It also has the so-called manual control function, which generally refers to the human ability to ...
